ADSORPTION OF COPPER FROM METAL INJECTION MOLDING INDUSTRY EFFLUENT USING RICE HUSK AS ADSORBENTAKSHATHA K.U., HINA KOUSAR AND CHAITHRA C.Abstract In the present study, rice husk as an adsorbent has been used for removing copper from metal injection molding industry effluent. Adsorption was carried out in a batch experiment with initial concentration of copper by varying the amount of adsorbent, pH and reaction time, under constant shaking of 100 ml sample in a heavy rotatory shaking apparatus for 2 hours. After treatment, the result revealed that about 93.32% of copper was reduced at pH7 with 8 g rice husk. Physicochemical analysis before and after treatment was also carried out. Brunauer Emmett Teller (BET) analysis was carried out for Specific surface area, Pore volume and Average pore diameter of rice husk. Scanning Electron Microscopic (SEM) analysis was carried out for structural and morphological characteristics of rice husk. To determine the concentration of copper before and after treatment, Atomic Adsorption Spectrophotometer was used. |
